Another pest that may affect this plant is the leafhopper. This can cause stippling or yellowing of leaves and may also spread diseases. To manage this issue, remove any affected leaves and use an insecticide if necessary.
Preventative Measures
To prevent diseases and pests from affecting Lessertia astragalina Pappe, it is important to maintain good plant health by providing proper growing conditions.
